ELECTRIC GAS-LIGHTER.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application led January Z, 1904:. Serial No. 187,547.

To all whom t may concern:

woc, in the county of Manitowoc and State of Wisconsin, have invented a new and luseful Electric Gas-Lighter, of which the following is a specification.

My invention relates to an electric gaslighter which operates by turning the gascock which allows the gas to enter the burner for illumination or heating. I attain this object by a mechanism and electrical conduit, as illustrated in the accompanying drawings, in which- Figure l is a side elevation of the entire gas-burner as commonly7 in use to which my newly-invented device for lighting gas is connected; Fig. 2, a vtop view of the burner. Fig. 3 is a central longitudinal section as seen from the dotted line 3 3 on Fig. 2.

Similar letters refer to similar parts throughout the several views.

A is a gas-pipe leading to burner O, with a cock B, as commonly used. Electrical conductors D and E, connected to any electric generator, may pass through the inside of the said gas-pipe, as the drawings show, or placed outside, end in electrical poles Gr and F close above the burner. Pole Fis madel stationary in'its position, while pole Or is connected to gas-cock B by members J and L, of which L is anon-conductor, insulating conductor D from the metal parts of the burner. Conductor D passes through a non-conducting member H, clamped to burner by band I, allowing D to revolve with cock B.

When cock B is closed, pole G is in position a, Fig. 2, and no electric current is flowing; but if cock B is opened 'by turning same from position @toward b, Fig. 2, it will make an electrical contact with pole F after making an angle of forty-five degrees. In this position gas will flow through the burner, and in opening cock B farther-that is, turning it farther toward -the electric contact betweenpoles G and F will be broken, and

the electric spark emitting from the poles Gr and F will light the gas. When cock B is quite open, the electric circuit is broken and no current is ilowing. It is apparent that only at the moment of contact of poles G and F a current is flowing.

Members K are insulating-plugs through which the `electrical conductors or wires D and E pass from within the gas-pipe A.

This device can be attached to any gasburner now in use either for light or heating.

I am aware that prior to my invention electric gas-lighting devices have been made. I therefore do not claim such broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

In an electric gas-lighter, the combination with a gas-xture having a burner'and a stopcock therefor, of electric conductors D and E adapted to enter said gas-fixture near the burner and extend therein to the source of electric supply, insulating-plugs K adapted to insulate vsaid conductors from said xture,

conductor D terminating at its upper end in a pole Or and conductor E in a pole'F, said conductor E being secured stationary to the burner while the conductor D is rotatably secured thereto, a band I surrounding the upper end of said burner adapted to dispose the pole G in juxtaposition to the pole F, an insulatqr H carried by said band through which said conductor D passes, said conductor being rotatable therein, and means to rotate said conductor comprising an L-shaped member J one end of'which is ixedly secured to the cock B and has secured to its opposite end the conductor D whereby, when the cock is turned to release the yflow of gas, the pole G will be brought into contact with the polc F and a spark produced to ignite the gas, saidconductor being insulated from the member J by an insulating member L, as set forth.
